Sorry, but out of the box there isn't. A couple of suggestions:
For Actions, if you change/clean up the name of the Source to be Module.View or if the source is in a different model (Model.Module.View), that will help. It will not be a fun chore if you already have a model up and running, but it will help in identifying which views are being used as well as potentially cleaning up unused/unneeded actions
In the modules area, you can see which modules are used in Dashboards. From here, you can open the module and see if any views are defined and clean those up. The majority of issues we see are views with multiple filter criteria on the same tab. Additionally, as stated in the video, only have the line items that are truly needed for the action or target module.
And please remember, as of now, there is not a way to see if filters on views are using line items from a different module (SYS Time, for instance). So, in this scenario, it is best to use the Notes functionality on the line item in SYS Time (filter module) to signify it is being used as well as where it is being used.
